Didn't most of those kosovar/macedonian operated fake news farms turn out to be just random private citizens from those countries taking advantage of the situation instead of a massive Russian-run operation? If russia actually ran tons of pages and controlled the narrative we would've known by now using the same tools used to unmask the balkan troll farms. I'm sure some were intelligence operations but do we have proof that those really had any big influence on public discourse?

Unless you are saying that russia could do the same in the future, which I agree is possible but we would still ultimately end up knowning about it. The anti nuclear movement in europe is pretty grassroots and the fact is that we don't have any proof of substantial russian influence on that subject even if everyone is much more on the lookout (as your links indicate)
